If i remove this bean from my xml it will build and deploy fine:
Code:
    <bean id="sessionFactory"
    		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    		<property name="dataSource" ref="dataSource"></property>
    	</bean>
The rest of my xml content is this:

Code:
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee"
